I really don't see why so many players are against mac players.
Well, I've mostly play on UKCS servers and they're not against any kind of player.
They're friendly people.
But yeah ... the steam forum is full of hatred to the mac players.
I do think valve should have given something to pc players as well, but there isn't really a specific wearable item for microsoft I guess.

I understand that a lot of people don't like using macs (I also prefer PC), but really I don't see how it makes a difference in TF2. I mean... really? Refusing to heal a mac player? What the hell? Maybe all the hate is just a big joke.
